Question 1:D

Question 2:C

Question 3:C

Test analysis:

Question 1: On the date in the picture, the sun shines directly on the Tropic of Capricorn, and there is an extreme night phenomenon in the Arctic Circle and its north, and an extreme day phenomenon in the Antarctic Circle and its south. This is the winter solstice in the northern hemisphere. So choose option d in this question.

Question 2: The date of winter solstice in the northern hemisphere is about 65438+February 22nd. Labor Day is 1 May, Children's Day is 1 June, Christmas Day is 65438+February 25th, and National Day is 1 October. So this question chooses option C.

Question 3: Jinghong in Yunnan is located in the northern hemisphere. When the sun shines directly in the southern hemisphere, the days in the northern hemisphere are short and the nights are long. The higher the latitude, the shorter the day, and the extreme night phenomenon near the North Pole. So this question chooses option C.

Comments: According to the position of the direct point of the sun, the position of the earth in the orbit of revolution, and the length of day and night in the northern and southern hemispheres, we can judge the solar terms of the earth. From summer to morning in the northern hemisphere (around June 22), the sun shines directly on the Tropic of Cancer, the days in the northern hemisphere are long and the nights are short, and the Arctic Circle and its north are extremely day. During the winter solstice (about 65438+February 22nd), the sun shines directly on the Tropic of Capricorn, and the days in the northern hemisphere are short and the nights are long, and the Arctic Circle and its northern region are extremely night. At the equinox, the sun shines directly at the equator, and the whole world is as long as day and night.
